I take on flower corvettes on the surface most of the time my crew last night took on a Black Swan on the surface,(I thought they were takeing out stragglers from a convoy I just demolished)

I had too take the deck gun myself although she was a blazing wreck all her forward guns were destroyed but her rear gun was still intact but after about 20 rounds of HE into her she went down,won't be doing that again in a hurry.
